To understand a dog, watch the whole body and what is happening nearby. A wagging tail, yawn or lip lick has no single translation. Posture, muscle tension, the distance a dog seeks and changes when someone approaches all matter.
Signs of comfort
A comfortable dog often moves fluidly, has a loose body and can explore, sniff or rest. They may approach by choice and move away without difficulty. During play, check whether both dogs take turns and can pause; high excitement does not always mean both are enjoying themselves.
Dogs do not all look alike when relaxed. Ear, tail and facial shapes differ between breeds and individuals. Learn what your own dog looks like at ease so changes stand out.
Signs that more space may be needed
Moving away, hiding, freezing, stiffening, turning the head or avoiding eye contact may indicate discomfort. Panting when it is not hot, repeated yawning or lip licking can also appear with stress, though none diagnoses a problem by itself. Take a growl seriously as communication and increase distance rather than punishing it.
Consider the sequence: what happened just before the signal? Did a visitor, child or another dog approach? Could your dog retreat? Refusing a normally valued treat may mean that the current situation is too difficult.
Respond to the message
Allow space when your dog seeks it. Avoid leaning over, hugging or touching a dog while they eat or sleep. Teach children to wait for a dog to approach voluntarily and supervise interactions. If dogs are tense with each other, separate them safely without putting hands between mouths.
Body signals can guide puppy socialisation and help explain why a dog pulls on the leash or barks when alone. Similar-looking behaviour can have different causes; context prevents a quick but wrong conclusion.
If fear is intense, aggression appears, pain is possible or behaviour changes suddenly, consult a vet and qualified behaviour professional. A body-language guide helps observation; it cannot replace an individual assessment.
